On 11 November, Gazprom International, the sole specialised operator of Gazprom’s foreign upstream projects, completed testing of the Begumganj-3 well, drilled for BAPEX, in the southeast of Bangladesh. As a result, a maximum influx rate of 642,000 m3 of gas per day was obtained.
The overall depth of the well totalled 3565 m and the perforation interval came to 2,895-2,900 m.
This is the third of ten planned wells that Gazprom International began drilling in July of this year under a contract with the Bangladeshi companies BAPEX and BGFCL/SGFL.
Drilling is also currently under way at the Titas gas field, at the Titas-21 well, whose projected depth is 3,790 m.
In April 2012, Gazprom International signed two contracts with BAPEX and BGFCL/SGFL, both subsidiaries of the state-owned Petrobangla (Bangladesh Oil, Gas and Mineral Corporation) to design and construct 10 wells. Under the contract with BAPEX, the drilling of five wells is planned: four wells in the Titas field and one in the Rashidpur field.
Under the contract with BGFCL/SGFL, the drilling of another five wells is planned: three in the Semutang, Begumganj and Shrikail fields (one well in each), and two wells in the Shahbazpur field. Most of the wells are directional wells. Their depth will range from 2,900 m to 4,050 m (down the wellbores).
Begumganj is a small gas field in Bangladesh, located 108 km to the southeast of the city of Dhaka. Begumganj lies in the Bengal Oil and Gas basin, opened in 1977. The productive interval is characterised by the presence of abnormally high formation pressures, which often makes it difficult to extract hydrocarbons. Initial geological reserves of natural gas are estimated at 1.1 billion m3 and recoverable reserves are estimated at 0.6 billion m3.
